I've got a page template called tpl-memos.php which is attached to a page called 'Memos' with a parent page called 'About', the permalink for the page therefor is example.com/about/memos. On this page a custom post type called 'info' is listing its posts, and this custom post type has a rewrite of '/about/memos' – the same as the page structure.

This is working pretty good: the posts from the CPT is listed and they get the correct URL, example.com/about/memos/%post_name% and of course it's a single-info.php file that is used to output the posts.

My only problem is that I can't seem to get the pagination correct, when clicking 'Previous posts' all I get is a 404 error.
